Answer :

Let's solve the given problem step-by-step:

1. Write [tex]\( (64)² \)[/tex] without using exponents. This means we need to express the square of 64 as multiplication:

[tex]\[ (64)² = 64 \times 64 \][/tex]

2. Multiply the two numbers together:

[tex]\[ 64 \times 64 = 4096 \][/tex]

So, the final result is:

[tex]\[ (64)² = 4096 \][/tex]

Therefore, filling in the blank, we get:

[tex]\[ (64)² = 4096 \][/tex]
