Question

Need help ASAP!!!!!!!

Evaluate each expression for the given values of the variables.

1. 3x · 2 ÷ y; x = 3 and y = 6

2. (4a)^3 ÷ (b − 2); a = 2 and b = 4

Answer 1

1. 3 2. 16

Explanation:

3x+2/y, x = 3 and y = 6

3(3)/6

Factor the number

3*3*2/3*2

Cancel the common factor (3)

3*2/2

Cancel the common factor (2)

3/1

Simplify

=3

(4a)^3/(b-2), a = 2, b = 4

(4(2)^3/(4-2)

Subtract the numbers:

2^3 * 4/2

Apply exponent rule (a^b*a^c=a^b+c)

= 2^3+1

Add the numbers:

2^4

Simplify:

=16
