Question

Помогите найти то, где есть log
спасибо.

Answer 1

1.7*7^log76=7*6=42
1. 2^5*2^log23=2^5*3=32*3=96
3. 3^2*7=9*7=63
4.6^3*2=432
5. 6*4=24
6. (11^log112)^-2=2^-2=14
7.(7^log73)^4=3^4=81

Answer 2

1) $7 ^{1+log _{7}6 } =7*7 ^{log _{7}6 }= 7*6=42$
2) $2 ^{5+log _{2} 3} = 2 ^{5} *2 ^{log _{2}3 }= 2 ^{5}*3=96$
3) $3 ^{2+log _{3} 7} =3 ^{2}*3 ^{log _{3}7 } =3 ^{2} *7=9*7=63$
4) $6 ^{3+log _{6}2 }= 6 ^{3} *6 ^{log _{6} 2} =6 ^{3} *2=216*2=432$
5) $6 ^{1+log _{6}4 }=6*6 ^{log _{6}4 }=6*4=24$
6) $11 ^{-2log _{11}2 }= (11 ^{log _{11}2 } ) ^{-2} =2 ^{-2} = frac{1}{2 ^{2} }= frac{1}{4}=0,25$
7) $7 ^{4log _{7}3 }=(7 ^{log _{7} 3}) ^{4} = 3 ^{4}=81$
