Which expression is equivalent to this one??? Cuhhhhhhhhhh...,,,!!!
bogdanovich [222]

Answer : The equivalent expression of the given expression is 1.

Step-by-step explanation :

According to the BODMAS rule, when the expression contains brackets open ((), {}, []) we have to first simplify the bracket followed by of (powers and roots etc.) and then we have to solve the division, multiplication, addition and subtraction from left to right order (respectively).

The given expression is:

(11²)⁴ ÷ 11⁸

First we have to solve bracket.

= (11)⁸ ÷ 11⁸

By dividing this expression, we get:

= 1

Therefore, the equivalent expression of the given expression is 1.

What is 8.25+1/4w=10.75
stepladder [879]

Answer:

w = 10

Step-by-step explanation:

Solve for w:

w/4 + 8.25 = 10.75

Put each term in w/4 + 8.25 over the common denominator 4: w/4 + 8.25 = w/4 + 33/4:

w/4 + 33/4 = 10.75

w/4 + 33/4 = (w + 33)/4:

(w + 33)/4 = 10.75

Multiply both sides of (w + 33)/4 = 10.75 by 4:

(4 (w + 33))/4 = 4×10.75

(4 (w + 33))/4 = 4/4×(w + 33) = w + 33:

w + 33 = 4×10.75

4×10.75 = 43:

w + 33 = 43

Subtract 33 from both sides:

w + (33 - 33) = 43 - 33

33 - 33 = 0:

w = 43 - 33

43 - 33 = 10:

Answer: w = 10
