5^x*2^3=36
5^x=36/8
5^(x+1)=5^x*5^1=36*5/8=45/2
Hence the right option is 7👍

first equation gives 5^x = 9/2
then use the formula

5^x * 2^3 = 36
5^x * 2^3 = 2^2 * 9
5^x * 2 = 9
5^x = 9/2
5^(x+1) = (9/2) * 5
5^(x+1) = 45/2

First we find value of x

as

5^x=36/8

xlog5= log4.5

x= log4.5/ log 5

then we put value of x in 2nd equation

5^(x+1) we get 22.49 approx 22.5 as answer

Mukund Manohar   7 years AGO

5^x * 2^3 = 36
=> 5^x = 4.5
=> 5^x = 5^0.935
x = 0.935
So, 5^(x+1) = 5^(1.935) = 22.5 = 45/2

somaiah tummala   7 years AGO

given 5^x*2^3=36

5^x*2^3=3^2*2^2

then,
=> 5^x*2=3^2
=>5^x=9/2
now
=>5^(x+1) (from a^m*a^n=a^(m+n))
=>5^x*5^1 -----(1)
substitute 5^x into eqn(1)
=>9/2*5 -----(*here 5^1=5)
=>45/2
so answer is option 7

yamini velaga   7 years AGO

5^x =36÷(2^3) = 4.5
x = log 4.5 ÷ log 5
x= 0.9345
5^(x+1) = 5^ (0.9345+1) = 22.5 = 45

Saptarsy Chakraborty   7 years AGO

5^x*2^3=36
, 5^x=9/2
, xlog5= log(9/2)
Therefore, x= log(9/2)/log5.
Now, 5^(x+1)=(x+1)log5 (taking log)
= ((log(9/2)/log5)+1)*log5 (putting value of x)
= log(45/2) = (taking antilog /removing log) 45/2

Multiplying 5 on both sides.
5^x * 2^3 * 5 = 36 * 5
Solving we get
5^(x +1) = 45/2
