What is the simplified form of the expression? (b/7)^2

The simplified form is

Step-by-step explanation:

The goal of the exercise is to apply exponent properties. On this case we need to distribute the exponent to each expression of the fraction, that is to the numerator and to the denominator, using the distribution exponent property.

In a general way we can always distribute exponents over multiplication or division.

Simplifying using exponent distribution property.

Applying the property to the exercise give us

Lastly we know that so we get

And that is the simplified form of the given expression.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
