Answer:
Step-by-step explanation:
Given the expression 4^{-2}•7^{-2}. The following expression are equivalent to given expression on simplification.
Generally from indices, a^-b = 1/a^b. Applying this to the given expression we have:
4^{-2}•7^{-2} = 1/4^2 • 1/7^2
= 1/(4×4) • 1/(7×7)
= 1/16 • 1/49
= 1/(16×49)
= 1/784
Wait i don’t understand how they are fractions. lmk
64 ft² X <span>0.5=32ft²
</span>What is the surface area of the reduction? 3<span>2ft²</span>
$350 I invested in my account
1.2% I earned in interest
Multiple it together
You earned $4.20 in one year.
In 10 years multiple by $4.20=$42.00
28(pi) is the same thing is (pi)(diameter)
so 28/2 is 14
14 is the radius
