Step-by-step explanation:DO exponent first which is 5 to the power of 2 .And 5 to the power of 2 equals to 25.Now following pemdas,do multiplcation first.So do 25 times 4 which gives you 100.Lastly add 3 to 100 which is 103.
We have to rewrite the expression so that it has no denominator. For example: 1 / x = x^(-1) 1/8 = 8^(-1); 1/x^(4) = x^(-4); 1/y^(3) = y^(-3); 1/z = z^(-1).
