Tolong Jawab pakai caranya nomor 3 dan 4

3) 5^-4 + 25^-2= 1/5⁴+1/25² = 1/625+1/625= 2/625 ( jawabannya "A")

4). 2√3×4√12= (2×4)√3×√12 = 8√36 = 8√4.9 = 8×2√9 = 16×3 =48

[tex]3.)5 { - }^{4} + 25 { - }^{2} = 5 { - }^{4} + 5 { - }^{4} \\ = 2 \times 5 { - }^{4} \\ = 2 \times \frac{1}{5^{4} } \\ = \frac{2}{5^{4} } \\ = \frac{2}{625} \\ \\ \\ 4.)2 \sqrt{3} \times 4 \sqrt{12} = 2 \sqrt{3} \times 4 \times2 \sqrt{3} \\ = 2 \times 3 \times 4 \times 2 \\ = 48[/tex]
jawab :

3.) A. 2/625
