Explanation:
Recall that an exponent represents the number of times the base is multiplied by itself.
For instance, in your case,
-7^2
ul("where") :
base=7
exponent=2
the expression means to multiply
Hence,
=-(7xx7)
=-(49)
=color(green)(|bar(ul(color(white)(a/a)color(black)(-49)color(white)(a/a)|)))
