Tolong bantuannya sama caranya plissss

[tex]a.(3 { - }^{2} \times \frac{3}{5}) {}^{2} [/tex]
[tex] = \frac{3 { - }^{1} }{5} {}^{2} \\ = \frac{1}{5 \times 3} {}^{2} \\ = ( \frac{1}{15} ) {}^{2} \\ = \frac{1}{225} [/tex]
[tex]bentuk \: alternatif \\ = 0.00444444[/tex]

[tex]b.( - 2 + 3) {}^{3} (5 - 3) {}^{3} { + }^{1} (3 - 1) {}^{3} { + }^{2} [/tex]
[tex] = 1 {}^{3} \times 2 {}^{4} \times 2 {}^{5} [/tex]
[tex] = 2 {}^{9} [/tex]
[tex]bentuk \: alternatif \\ = 512[/tex]
*semoga membantu*
*jadikan jawaban terbaik yah*

A. (3-² x 3/5)²
= 1 /225
b. (-2+3)³(5-3)³+¹(3-1)³+²
= 1³x 2/4 x 2⅝
=2 9
=3-¹/5 ²
=(1 /15 )²
=1/225.
bentuk alternatif = 0.00444444
semoga membantu. jadikan jawaban terbaik y.
