Answer:
3h - 2
Step-by-step explanation:
An expression is a mathematical phrase using variables, such as 'h', and operations, such as addition, subtraction or multiplication. An expression does not include the equal sign (=).
The problem asks you to use the variable 'h' which we can substitute for 'a number' in the verbal description. Also, 'difference' is a word used for the operation of subtraction. 'Times' is a word that we use for the operation of multiplication. So, 'three times a number' = 3h. 'The difference of three times a number and two' = 3h - 2.

Answer:
3:5 is the answer of your question
When you add, you subtract the exponents. When you divide, you subtract the exponents.
When you have multiplication and division in one expression, you do it from left to right.
7^2 times 7^5 = 7^ (2+5) = 7^7
7^7 times 2^2 / 7^3 = 7 ^(7 - 3) times 2^2
7^4 times 2^2 times 2^6 = 7^4 times 2^(2+6) = 7^4 times 2^8
Put it in a calculator.
614656.
That is the answer, but you didn't include the "which of the following", so I guess you'll have to put each value in the calculator to find out!
If the 7^3 times 2^6 is in parenthesis, then the answer is 150.0625.
