The expression 4 x b x b x b simplifies to 4b^3. This is because when you multiply the coefficients 4 and 1, you get 4. When you multiply the variables b, b, and b, you add the exponents, resulting in b^3. Therefore, 4 x b x b x b equals 4b^3.
A number a multiplied b times (so a x a is b=2, a x a x a is b=3, a x a x a x a is b = 4, and so on) is written as ab. Since 2 is multiplied 4 times, you have 24.
For the denominator, multiply the denominators together. For the numerator, subtract the second numerator multiplied by the first denominator from the first numerator multiplied by the second denominator: a/b - p/q = (a x q - b x p)/b x q eg: 6/7 - 3/4 = (6 x 4 - 7 x 3)/7 x 4 = (24 - 21)/28 = 3/28

okay if x-4=3 then x=7 bcause 4+3=x = 4+3=7 and 7-4=3!
