Answer:
The answers are
→ a. 15
→ b. 27
→ c. 4
→ d. 72
→ e. 2
→ f. 9
→ g. 1
Step-by-step explanation:
Given expressions:
a. 7 + 2³
b. 9 • 3¹
c. 20 - 2⁴
d. 2 • 6²
e. 8 • (1/2)²
f. 1/3 • 3³
g. (1/5 • 5)⁵
a. 7 + 2³
[tex]7+2^3[/tex]
[tex]2^3 = 8[/tex]
[tex]8 + 7 = 15[/tex]
Hence, 15 is your answer.
b. 9 • 3¹
[tex]9*3^1[/tex]
⇒ [tex]9*(3)[/tex]
⇒ [tex]27[/tex]
Hence, 27 is your answer.
c. 20 - 2⁴
[tex]20 - 2^4[/tex]
[tex]2^4 = 16[/tex]
[tex]20-16 = 4[/tex]
Hence, 4 is your answer.
d. 2 • 6²
[tex]2 * 6^2[/tex]
⇒ [tex]2*6^2[/tex]
⇒ [tex]2*(6*6)[/tex]
⇒ [tex]72[/tex]
Hence, 72 is your answer.
e. 8 • (1/2)²
[tex]8 * (\frac{1}{2})^2[/tex]
⇒ [tex]8*((\frac{1}{2})*(\frac{1}{2}))[/tex]
⇒ [tex]2[/tex]
Hence, 2 is your answer.
f. 1/3 • 3³
[tex]\frac{1}{3} * 3^3[/tex]
⇒ [tex]9[/tex]
Hence, 9 is your answer.
g. (1/5 • 5)⁵
[tex](\frac{1}{5} * 5)^5[/tex]
⇒ [tex]1*1*1*1*1[/tex]
⇒ [tex]1[/tex]
Hence, 1 is your answer.
