Question

i can evaluate expressions that have exponents. evaluate each of the expressions below. remember that means find the answer! you may use a calculator and/or a multiplication chart. 1. $3^{2}cdot2^{2}=$ 2. $10^{2}+3=$ 3. $2^{3}+5^{2}=$ 4. $3^{2}cdot7=$ 5. $5cdot4^{3}=$ 6. $8^{2}+10=$ 7. $1 + 13^{2}=$ 8. $5^{2}cdot3=$ 9. $12^{2}+7^{2}=$ 10. $2cdot3^{3}=$

Explanation:

Step1: Calculate exponents first

1. $3^{2}=9$, $2^{2}=4$, so $3^{2}\cdot2^{2}=9\times4 = 36$
2. $10^{2}=100$, so $10^{2}+3=100 + 3=103$
3. $2^{3}=8$, $5^{2}=25$, so $2^{3}+5^{2}=8 + 25=33$
4. $3^{2}=9$, so $3^{2}\cdot7=9\times7 = 63$
5. $4^{3}=64$, so $5\cdot4^{3}=5\times64 = 320$
6. $8^{2}=64$, so $8^{2}+10=64 + 10=74$
7. $13^{2}=169$, so $1+13^{2}=1+169 = 170$
8. $5^{2}=25$, so $5^{2}\cdot3=25\times3 = 75$
9. $12^{2}=144$, $7^{2}=49$, so $12^{2}+7^{2}=144 + 49=193$
10. $3^{3}=27$, so $2\cdot3^{3}=2\times27 = 54$

Answer:

1. 36
2. 103
3. 33
4. 63
5. 320
6. 74
7. 170
8. 75
9. 193
10. 54
