Answer:
1. 32
2. 36
3. 1/5
4. 1/8
6. 729
7. 32
8. 72
9. 8
Step-by-step explanation:
1. Ans: 32
Solution: 2^5 = 2*2*2*2*2 = 32
2. Ans: 36
Solution: 6^2 = 6*6 = 36
3. Ans: 1/5
Solution: 5^-1 = 1/(5^1) = 1/5
if the exponent is negative, just take its reciprocal then the exponent will be positive and solve for the final answer. On this case, 5 raise to negative 1 will be, "1 over, 5 raise to 1".
5^1 is simply 5 so the final answer is 1/5.
4. Ans: 1/8
Solution: same explanation as no.3. so in this case it will be "1 over, 2 raise to 3"
2^3 = 8, so the final answer is 1/8
6. Ans: 729
Solution: on this case. Just multiply the exponent. So,
(3^3)^2 = 3^(3*2) = 3^6 = 3*3*3*3*3*3 =729
7. Ans: 32
Solution: If multiplying with similar bases, just add the exponents and copy the base.
(2^3)(2^2) = 2^(3+2) = 2^5 =2*2*2*2*2 = 32
8. Ans: 72
Solution: If multiplying with two diffrent bases, just compute individually.
(3^2)(2^3) = (9)(8) = 72
9. Ans: 8
Solution: "1 over, 2 raise to negative 3". Solve first the denominator, so it's the same to no. 4, so it is 1/8.
Now that is your denominator.
1/(1/8), to simplify this, just note that dividing two fractions, we take the reciprocal of the divisor then proceed in multiplication.
On this case, we can separate the numerator and denominator as two fractions. So,
1 is equal to 1/1
and copy 1/8
1/1 divided by 1/8
[1/8 is the divisor, so reciprocate. It would be 8. Then proceed multiplication]
1/1 * 8 = 8
