Problem 5)
The bases are the same, so we add the exponents when multiplying something like this out. We have -5+7 = 2 as the final exponent meaning that 5^2 = 25
<h3>Answer: Choice B) 25</h3>
=============================================
Problem 6)
We can multiply the exponents (t^8)^2 = t^(8*2) = t^16
Or we can expand out (t^8)^2 to get (t^8)*(t^8), then add the exponents from here to get t^(8+8) = t^16. Either way we get the same answer
<h3>Answer: Choice C) t^16</h3>
=============================================
Problem 7)
The negative exponent indicates we will apply the reciprocal to get that exponent to a positive number. The rule is x^(-k) = 1/(x^k)
So 5^(-4) = 1/(5^4) = 1/625 and (t^3)^(-4) = t^(3*(-4)) = t^(-12) = 1/(t^12)
Put together, we end up with 1/(625t^12)
<h3>Answer: Choice C) 1 over 625t^12</h3>

Let's solve your inequality step-by-step.
5>0.6(10+n)
Step 1: Simplify both sides of the inequality.
5>0.6n+6
Step 2: Flip the equation.
0.6n+6<5
Step 3: Subtract 6 from both sides.
0.6n+6−6<5−6
0.6n<−1
Step 4: Divide both sides by 0.6.
0.6n

Answer:
<h3>x = -14</h3>
Step-by-step explanation:
Given the equation
1/4x +4 = 1/2
Solving for x
Subtract 4 from both sides
1/4x +4 - 4 = 1/2 - 4
1/4 x = (1-8)/2
1/4 x = -7/2
Cross multiply
2x = -7*4
2x = -28
x = -28/2
x = -14
Hence the value of x is -14
