Answer:
1. True
2. False
3. True
4. True
5. True
6. True
7. True
8. True
9. False
10. False
11.True
12.
13.True
14. False
15. False
Step-by-step explanation:
1. 3³ × 3² = 243
27 × 9 = 243 (true)
2. 2⁰ = 0
1 ≠ 0 (false)
note: any number or variable raised to 0 or having an exponent 0, it is ALWAYS equal to 1.
3. 5^(-3) = 1 / 125
1/ 5³ ? 1 / 125
1/ 125 = 1 / 125 (true)
4. 8^ (2/3) = 4
cubed root of 8² = 4
cubed root of 64 = 4
4 = 4 (true)
5. 16 ^ (1/4) = 2
fourth root of 16 = 2
2 = 2 (true)
6. True
7. True
8. true
9. False - exponents should be multiplied
10. False - exponents should be subtracted
11. True
12. (a + b) ⁰ = 1 (any number/ variable raised to 0 is always equal to 1 )
13. 8^ (2/3) = 4
cubed root of 8² ? 4
cubed root of 64 = 4 (true)
14. 5^ (-2) = 1/15
1/ 5² ? 1/15
1/ 25 ≠ 1/15 (false)
15. 4^(1/2) = 1/ _
square root of 4 = 1/_
2 ≠ 1/_ (false)
