Welcome to Brainly, Dolly!

49 factors into 7^2.  7 is prime, and 49 is the square of this prime factor.

56 = 7(8), but 8 itself is the cube of 2.  Thus, 56 = 7*2^3:  7*2*2*2.

42 = 7(6) = 7*2*3

How do I round off to the nearest decimal place​
Marrrta [24]
First, find the digit in the place you are rounding to. Look at the digit one place to the right. If the digit is less than 5, round down. If the digit is 5 or greater, round up.
For example: round 1.86 to the nearest tenth
Look at the tenth digit (8). The number to the right of it is 6. Since it’s above 5, round the 8 up to 9. So you would get 1.9.

If it was 1.84, since 4 is less than 5, you would not round the 8, and you would get 1.8
