Answer:
100
Step-by-step explanation:
because it is directly proportional so 4 times ten is 40 and 10 times 10 is 100
pls mark brainliest it would really help me out
Answer:
19÷9=23
Step-by-step explanation:
correct me if I'm wrong

If there was a number other than 0 before the decimal point, it would serve as the whole number in our final answer.
First count the number of digits after the decimal point. For this problem it's 4.
Then make the denominator 10 raised to the power of your answer in the first step so the denominator for this question is 10⁴=10000
The numerator will be the number after the decimal point.
The fraction will be = 112/10000
Then reduce it to the lowest term
If you divide the numerator and denominator by 16 you get
7/625 which is the lowest possible fractional term.
Step-by-step explanation:
Given that:
a = 2ˣ
b = 2ˣ⁺¹ = 2ˣ * 2¹ = 2.2ˣ
Now,
{(8a³)/b²}
Substitute the value of x and y in expression then
= [{8(2ˣ)³}/(2.2ˣ)²]
= [(8*2³ˣ)/{2² * (2ˣ)²}]
= {(8*2³ˣ)/(4 * 2²ˣ)}
[since, (aᵐ)ⁿ = aᵐⁿ]
= {(2 * 2³ˣ)/2²ˣ}
= {(2 * 2²ˣ * 2ˣ)/2²ˣ}
[since (2a = a+a, that means 3x = 2x + x)]
= 2 * 2ˣ
= 2ˣ⁺¹
[since (aᵐ * aⁿ = aᵐ+ⁿ)]
<u>Answer:</u> Therefore, {(8a³)/b²} = 2ˣ⁺¹ .
