6 Ismail orders some logs for his open fire. The mass of one log is 2 kg. There are 5 logs in each bag.
Ismail orders 150 bags.
a What is the total mass of the logs Ismail orders?
Give your answer in tonnes.
b What is the total amount that Ismail pays for the logs?

12/11c

or

12

c

11

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube
