5 x 5 x 5 x 5 x 5 is five 5's multiplied by each other; when writing an exponent, use the form Bx, where 'B' is the base(the number being multiplied by itself), and 'x' is the exponent(how many times the base is being multiplied). Here, it would thus be written as 55.

You would write it as 93

Assume the expression is:4/(x + 2) + 6/(x + 5)Simplify this expression by combining the expressions altogether. Let's go step by step.Step 1: Determine the LCD of the expression.The LCD of the expression is (x + 2)(x + 5). Multiply the top and bottom of each fractional expression by whatever factor the denominator is missing!4/(x + 2) * (x + 5)/(x + 5) + 6/(x + 5) * (x + 2)/(x + 2)Step 2: Combine the expression and simplify.(4(x + 5) + 6(x + 2))/((x + 2)(x + 5))= (4x + 20 + 6x + 12)/((x + 2)(x + 5))= (10x + 32)/((x + 2)(x + 5))
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.

5 x 5 x 5 x 5 = 54 .
5 x 102
5 x 5 x 5 = 51+1+1 = 53 5 x 52 x 56 = 51+2+6 = 59 (5)3 = 51x3 = 53 (52)4 = 52x4 = 58

5000 = 5 x 1000 & 1000 = 10 x 10 x 10 = 2^3 x 5^3 Hence in exp in exponential form 5^(1) x 2^3 x 5^3 Remember for exponents, when multiplying with a common coefficient, you add the exponents(indices) Hence 2^3 x 5^(1 + 3) = 2^3 x 5^4
23 x 32 x 5 x 7 = 2520
the real answer is 5^4
x/7
I think the word you're looking for is "exponential". A linear expression is of the form ax + b whereas an exponential expression is of the form x^a + b.
