Help me with the x (what I got wrong)

Function Value f(x) = 10g49 X x = 7 Step 1 Substitute 7 for x in the function. 9 7 = 10949 7 27 Step 2 Notice that \\ 49 = 7. Rewrite without the square root symbol. 49 1/ 2 0 2 =7 Step 3 Recall the Power Property of logarithms which states that if a is a positive number and n is a real number such that a # 1 and if u is a positive real number, then log.(un) = n log=(u). Use this property to simplify the expression. log49(49) 10949 491/2 49 X
