A collection of dimes is arranged in a triangular array with 17 coins in the base row, 16 in the next, 15 in the next, and so fo

Crazy boy [7]

Answer:

153 coins will be there.

Step-by-step explanation:

The number of coin in the bottom row / or last row = 17

The number of coins in the second last row = 16

The number of coins in the second row = 2

The number of coins in the first row = 1

So the total number of coins = (Number of coin in the first row) + (Number of coins in the second row) + (Number of coins in the third row) + ....... + (Number of coins in the last row / seventeenth row)

Total number of coins = 1+2+3+....+16+17

Total number of coins = $\frac{17\times(17+1)}{2}=\frac{17\times18}{2}=17\times9=153$

(NOTE: Sum of first n natural number = $\frac{\boldmath n\times(n+1)}{2}$ )

Solution

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given logarithmic expression

$\log_4x=1.7$

STEP 2: Find the value of x

State the rule of logarithm that applies

$if\text{ }\log_ab=c,b=a^c$

Apply the rule

$\begin{gathered} \log_4x=1.7 \\ \therefore4^{1.7}=x \\ by\text{ simplification,} \\ 10.55606329=x \\ x\approx10.56 \end{gathered}$

Hence, the value of x is approximately 10.56
