I think it’s 104,974
Because PEMDAS,
so first deal with exponents and 3 to the fourth power is 81. 6 to the fourth power is 1,296.
Next in PEMDAS is multiplication and division, so 1,296 times 81 is 104,976. Then 4 divided by 2 is 2.
Finally comes subtraction, 104,976 minus 2 = 104,974

Which is bigger 3/8 or 0.3
Luba_88 [7]
\frac{3}{8} \\
0.3=\frac{3}{10}

If two fractions have the same numerator, the fraction with the smaller denominator is bigger.
8\ \textless \ 10 \Rightarrow \frac{3}{8} \ \textgreater \  \frac{3}{10}

3/8 is bigger.

∠Q = ∠G = 55°( corresponding part )

∠R = ∠F = 60° ( corresponding part )

∠S = ∠E = 65° ( corresponding part )

QS = GE = 16 ( corresponding part )

Therefore , the correct answer is :-

Use the digits 1,2,3 and 4 once each to get the largest answer possible
sukhopar [10]

Answer:

4,321

Step-by-step explanation:

This is the answer because:

1) We know that if the number has to be big therefore, we have to put 4 in the thousands place because 4 is bigger than 3, 2, and 1

2) Next, 3 is the other biggest number, for that reason 3 is in the hundreds place

3) Then, 2 is the other bigger number; therefore, the tens place is 2

4) Finally, the last number remaining is 1, which is in the ones place

Therefore, the answer is 4,321

Hope this helps!
