AJUDAA!! Eu sou péssima em matemática !!!​

Answer 1

Resposta:

4.a) $4^{3} . 4^{2} = 4^{3+2} = 4^{5}$

b) $7^{4} .7^{5}= 7^{4+5} = 7^{9}$

c) $2^{6} .2^{4}= 2^{6+4} = 2^{10}$

d) $6^{3} .6= 6^{3+1} = 6^{4}$

e) $3^{3} .3^{2}= 3^{3+2} = 3^{5}$

5.a) $5^{4} :5^{2}= 5^{4-2} = 5^{2}$

b) $8^{7} :8^{3}= 8^{7-3} = 8^{4}$

c) $9^{9} :9^{2}= 9^{9-2} = 9^{7}$

d) $4^{3} :4^{2}= 4^{3-2} = 4^{1}$

e) $9^{6} :9^{3}= 9^{6-3} = 9^{3}$

6.a) $(5^{3} )^{2}= 5^{3.2}= 5^{6}$

b) $(8^{2} )^{5}= 8^{2.5}= 8^{10}$

c) $(3^{2} )^{2}= 3^{2.2}= 3^{4}$

d) $(7^{4} )^{2}= 7^{4.2}= 7^{8}$
