Question

100=(5)power b find b value​

Answer 1

(10)^2=5^b

taking log both side

log(10)^2=log(5^b)

2log10=blog(5×2/2)

2=blog10×1/2

2=b(log10+log1/2)

2=b(1+log1/2)

b=2/1+log1/2

Ans.

Answer 2

b is equal to 20.

Step-by-step explanation:

• When we talk about the different mathematical operations that can be levied between two terms, the possible operations are mentioned in the rules of BODMAS. This BODMAS rule has bracket, of as the second operation, division as the third operation, multiplication as the fourth operation and subtraction as the last operation.
• Here, we need to find the number that has to multiplied by 5 in order to get a final product that is 100.
• Now, let b be the unknown number that has to be multiplied by 5 in order to get a result of 100. Then, we will have, according to the given information, 100 = 5 * b.

Now, 100 = 5 * b.

Or, b = $\frac{100}{5}$

Or, b = 20.

Thus, we can say that 20 is the number that has to be multiplied with 5 in order to get a final result of 100.

Thus, b is equal to 20.
