7
--7 = +7
replace b with 7 so you must first multiply -3 by 7 which gives you -21. Subtract 25 more and you get -46, which is the answer.
343 is 7 to the power of 3 ( 7 x 7 x 7 = 343) To find 7 to the 3 power to the 2/3 power you multiply the exponents and raise 7 to that power: 3 x 2/3 = 2 7^2 = 49
The expression "three sevenths of y" can be written as (3/7)y. To find "4 less than three sevenths of y," you would subtract 4 from this expression, resulting in (3/7)y - 4.

7
(21-3)times(7+4)
6 meter + 3 to the third =6m-7
--7 = +7
An equivalent expression.
Writing 7 to the third power is easy. It is written like 7 with a small 3 on the right side.
7 lol
The value of the expression 8 is always 8, whatever f is.
replace b with 7 so you must first multiply -3 by 7 which gives you -21. Subtract 25 more and you get -46, which is the answer.

If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
