Which expression is equivalent to 5^-2 x 5^-1
Mrac [35]

When you multiply powers with the same base, you sum the exponents:

a^b\times a^c=a^{b+c}

So, in this case, you have

5^{-2}\times 5^{-1}=5^{-2-1}=5^{-3}

Given the function k(t)=2t−1: a. Evaluate k(2). b. Solve(k)=7.
Aleksandr-060686 [28]

Answer:

k(2) = 3

t = 4

Step-by-step explanation:

Given

k(t) = 2t - 1

Solving (1): k(2)

Take t as 2 such that t = 2

This gives

k(2) = 2 * 2 - 1

k(2) = 4 - 1

k(2) = 3

Solving (2): k(t) = 7

Substitute 7 for k(t)

7 = 2t - 1

Add 1 to both sides

7 + 1 = 2t - 1 + 1

2t = 8

Divide both sides by 2

t = \frac{8}{2}

t = 4
