Find LCM and HCF for the following a. prime product of 12=2^2×3
b. prime product of 15=3×5
c. prime product of 48=2^4×3
d. prime product of 72=2^3×3^2​

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

linear pair postulates

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x
