welcome to math with Mr J [Music] in this video I'm going to cover square roots and cube roots we will take a look at what both square roots and cube roots are the best way to do this is to jump right into our examples starting with number one where we have a 6 and 36. we are going to start by taking a look at square roots for numbers one and two and then we will move to cube roots for numbers 3 and 4. now in order to understand square roots we are going to start by looking at squaring a number for example let's do 6 squared now 6 squared that equals 36. remember squaring a number means to multiply it by itself so 6 squared means 6 times 6 which equals 36. so again 6 squared equals 36. now the square root of a number is the inverse or opposite of squaring a number we are going in reverse of squaring a number so to speak when it comes to square roots we need to think what number multiplied by itself will equal the number under the root symbol for example let's find the square root of 36 so what number multiplied by itself equals 36 well we know that 6 times 6 equals 36 so the square root of 36 is 6. again the square root of 36 equals 6. let's move on to number two where we have the square root of 49 well what number multiplied by itself equals 49 we know that 7 times 7 equals 49 that means that the square root of 49 equals 7. so there's a brief overview of square roots let's move on to cube roots and take a look at numbers 3 and 4. starting with number three where we have a 4 and a 64. now in order to understand cube roots we are going to start by looking at cubing a number for example let's do 4 cubed now 4 cubed equals 64. when we cube a number we multiply that number by itself three times so 4 cubed means four times four times four times four is sixteen times four is sixty-four so again 4 cubed equals 64. now the cube root of a number is the inverse or opposite of cubing a number we are going to go in reverse of cubing a number so to speak when it comes to a cube root we need to think what number multiplied by itself three times equals the number under the cube root symbol for example let's find the cube root of 64. so what number multiplied by itself three times equals 64. well we know that 4 times 4 times 4 equals 64. so the cube root of 64 is 4. again the cube root of 64. equals 4. let's move on to number four where we have the cube root of 27 so what number multiplied by itself three times equals 27 well 3 times 3 times 3 equals 27 3 times 3 is 9 times 3 equals twenty-seven that means that the cube root of 27 equals three so there's a brief overview of cube roots now to recap for square roots we need to think about what number multiplied by itself will equal the number under the root symbol for cube roots we need to think about what number multiplied by itself three times will equal the number under the cube root symbol so there you have it there's an explanation of square roots and cube roots I hope that helped thanks so much for watching until next time peace
