2^7 x 7^2

can someone explain how i am supposed to do this

Step-by-step explanation:

An exponent is a symbol written above and to the right of a mathematical expression to indicate the operation of raising to a power.

Example: 2^4

2x2x2x2 You multiply 2 by itself 4 times.

A lot of people get confused and multiply 2x4, which is wrong.

2x2=

4x2=

8x2=

16x2=

32x2=

64x2=128

So 2^7 is 128.

Now onto 7^2...

This, you just multiply 7x7, which is easy. 7x7=49

Now you multiply 128 and 49.

128x49=6272

hope it helps!
