The answer the 3,
First you have to apply the exponent rule which is 1 - 3• 1/g
Then you multiply the fractions - 1•3/g
Then multiply the numbers 1 and 3, which is 3, so there you have it 3/g, or 3, they’re the same thing.
Answer:
∠a=40°
Step-by-step explanation:
complement of angle a=90-a
supplement of angle a=180-a
90-a=1/2(180-a)-20
multiply by 2
180-2a=180-a-40
180-180+40=-a+2a
a=40
Answer:
Option C - 1/81
Step-by-step explanation:
9^(-2) = 1/(9^2) [ Because a^(-m) = 1/(a^m) ]
so, 1/(9²) = 1/81.
Hope this helps you.
